Overview Customization
	PDFDoclet allows to import additional pages from an external PDF document in
	addition to - or instead of - the regular overview. If the regular overview
	is used as well, the imported PDF pages are inserted 
before the regular
	overview pages, just after the title page.
	
	To import pages from an external PDF document, use this configuration property:
	
      overview.pdf.file=./doc-files/projectinfo.pdf,3-5
	
	The format of the string is the same as for PDF appendices (see 
	
appendices for more details).
	
	In order to distinguish between the imported pages and the regular overview,
	the use of custom bookmark entries in the regular overview can be useful
	(see 
bookmarks for details). If pages from a
	PDF document are imported, the default "Overview" bookmark will always point
	to the first of these imported pages.
